Definition: WISP

(Wireless ISP) An Internet service provider (ISP) that transmits wireless. Using WiMAX and other radio technologies, WISPs generally provide "last mile" connectivity directly to homes and businesses where DSL and cable services are not available.

Mobile Wireless
Carriers such as AT&T, Verizon and Sprint are technically "mobile WISPs;" however, they are generally called "cellular carriers" or "mobile carriers."

Fixed Wireless
In contrast, "fixed wireless WISPs" mount antennas on tall buildings with line of sight to their customers or to other antennas that relay the signals around obstacles. WISPs became popular in rural and outlying areas, because they were the only high-speed Internet connection available; however, they are increasingly being deployed in urban areas competing with the giant ISPs.
